Anionic polyacrylamide (APAM)
Anionic polyacrylamide (APAM) appears as white powder with a molecular weight ranging from 3 million to 25 million. It has good water solubility and can be dissolved in water and insoluble in organic solvents. The effective pH value range is 6 to 10. It has the characteristics of a high polymer electrolyte in a neutral alkaline medium, is sensitive to salt electrolytes, and can cross-link with high-valent metal ions to form an insoluble gel.
Product features of high-viscosity anionic polyacrylamide used for fragrance production:
1. Good solubility, high viscosity, strong toughness, flammable, no (little) smoke, no smell when burning, non-toxic, etc.;
2. The performance of the product is stable, which avoids the uneven bonding quality of other plant gum powders and ordinary starches due to different places and times of production. The formula needs to be repeatedly debugged during fragrance production to avoid unstable product quality;
3. The appearance of the incense products is smooth and smooth, well-formed and not easy to break;
4. It can be gelatinized with cold water, so there is no need to cook the paste. It can be produced by directly mixing the materials evenly and adding water and stirring. Moreover, the mixed materials after adding water will not become dry and hard to use if left for a long time. It is effective. It greatly saves energy and facilitates production operations
Packaging and storage of anionic polyacrylamide:
This product is a non-toxic powdery granular product that is easily affected by air, thus affecting its quality. Therefore, it should not be stored in a humid or sunny environment. In addition, during loading, unloading and transportation, it is necessary to avoid contact between PAM and iron and copper metals. Diaphragm pumps and piston pumps are preferred for delivery pumps. The storage period of solid granular or powdered polyacrylamide is 2 years.
